Brandt called the story "something I have never witnessed" in his half-century in pro football.

"I think some teams will say it isn't worth the problem" to draft Te'o, said Brandt, who has the linebacker rated 19th overall in the first round.

The former Cowboys general manager added Thursday that Te'o's stock had plummeted after a poor performance in the BCS championship game.

"I don't think anybody considered him to be a top-five pick before all this happened," Brandt said. "In that game against Alabama, this was like a guy who was the best shooter in the world in basketball and here comes a game and he can't even hit the backboard. His play in that game was absolutely horrible. He missed on run blitzes; guys ran over him ..."

Te'o would hardly be the first player to see his draft stock sink because of off-field issues. Chicago Bears general manager Phil Emery said "it's no different what the red flags are."

"You've got to identify them," he said. "You've got to research it and then you decide what impact that has on the total person in terms of his ability to play football and to manage his life."

David Schwab, a senior executive at sports management firm Octagon, considered Te'o perhaps the most marketable player coming into this year's draft. As the face of a Notre Dame team that returned to national relevance, the Heisman Trophy runner-up had the name recognition of few college stars.

"Compassionate" and "heartwarming" were some of the adjectives Schwab would have used to describe his image.

Now, that persona will depend on the details that emerge about the story of a girlfriend who didn't exist.

"If he truly had nothing to do with it, I think the long-term damage is zero," said Schwab.
